Title: Improvements relating to the manufacture of nuclear fuel elements
Inventor: ROBINSON JOHN ALBERT
IPC: G21C3/08
Filed: 1958-09-03
Abstract: 866,554. Making nuclear fuel elements; forging; extruding. A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd. Sept. 3, 1959 [Sept. 3, 1958], No. 28331/58. Classes 83 (2) and 83 (4). Finned canning for nuclear fuel elements is made by pressing a thick hollow cylinder 2 of canning metal by means of one or more surrounding dies 3 having recesses 4 for forming the fins 5. The fins may extend longitudinally, circumferentially or helically of the canning. Longitudinal supporting vanes 6 are formed simultaneously with the fins. In one embodiment the dies 3 are reciprocated radially of the cylinder 2 enclosing a rod of fissile material 1; alternatively the cylinder may be mounted on a mandrel in which case the finned canning is subsequently placed around the fissile material. In another embodiment (not shown) the hollow cylinder surrounded by a stationary annular die or a plurality of dies is expanded by a tapered mandrel to fill the recesses in the dies. The canning may be made of magnesium or aluminium and may be heated or cold.

Title: Improvements in and relating to typographical slug casting machines
IPC: B41B11/54
Filed: 1937-10-18
Abstract: 504,036. Pumps for molten metal. MERGENTHALER LINOTYPE CO. Oct. 18, 1937; Nos. 28352 and 28353. Convention dates, Oct. 31, 1936 and May 26, 1937. [Class 102 (i)] [Also in Group XVI] In order to prevent the drawing back of metal from the mould after the casting of a printer's type-bar, more especially in the case of large type-bars, which require a longer time for cooling, means are provided for delaying the withdrawal of the pump-plunger after its metal-injecting stroke. This may be effected (1) by automatic disengagement of the main driving-clutch of the machine, so as to arrest the rotation of the pump-controlling cam, or (2) by providing a mutilated gear in the driving- mechanism of the cam, so as to bring about a pause in its rotation. (1) The pump-plunger D, Fig. 1, is, as heretofore, depressed by a spring D<7> under the control of a lever D<2> and a cam D<9>. According to the invention, the stroke of the plunger, instead of varying with the amount of metal required to fill the mould, is made constant. To effect this, the plunger is provided with a port D<13>, Fig. 3, forming a byepass, through which metal can escape from the pump-well during the continued downward movement, of the plunger after the mould has been filled. The size of the port can be adjusted by means of a screwed valve-plug D<16>, and in the case of large type-bars, which require a longer time for cooling, the port is made smaller, so that the plunger takes a longer time to complete its stroke. During the descent of the plunger, an arm F on the pump-lever D<2> moves a slide F<2>, which is mounted in guides secured to the cam D<9>. A cam-piece F<4> on the slide acts through a lever F<6> to disengage the main driving-clutch, so that the cam is brought. to rest. After the cam-piece has passed the lever F<6>, the driving-mechanism is restarted. A delay, the length of which is controlled by the byepass in the pump-plunger, is thereby introduced before the plunger is raised. (2) In the second arrangement, the delay in the. return of the plunger is effected independently of its movement. The gear M<3>, Fig. 8, through which the pomp-cam D<9> is driven from a pinion M<2>, has three of its teeth removed, so that an interval of rest is provided for the cam. The cam is re-started by a segmental gear N, loosely mounted on the cam-shaft M, and also gearing with the pinion M<2>. During the rotation of the segment, an abutment N<4> thereon strikes one of the spokes of the gear M<3> and carries the multilated part past the pinion M<2>, so that the gear is again driven directly by the pinion. When the segment N passes out of gear with the pinion, it is returned to initial position by a spring. Adjustment of the abutment N<4> varies the length of the pause.

Abstract: 1,053,645. Graphite articles. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 9, 1964 [July 17, 1963], No. 28371/63. Heading C1A. [Also in Division G6] Graphite articles are produced by mixing a powder of graphite and/or graphitisable carbon with a binder consisting of dibenzanthrene vi olanthrene) or dibenzanthrone (violanthrone), pressing to form a shaped green body, heating to a carbonising temperature in the absence of air, and thereafter heating to a temperature in excess of the carbonising temperature. The pressing either may be at ambient temperature in the presence of a solvent for the binder, the solvent being removed under reduced pressure at a temperature of about 100‹ C. prior to heating the shaped green body, or may be at an elevated temperature in the absence of a solvent for the binder. Hot pressing may be at such a temperature, for example at from 750‹ C to 800‹ C., that carbonisation of the binder occurs during pressing; alternatively, the green body formed by hot pressing may subsequently be baked to carbonise the binder. After the pressing and carbonising steps, the article may subsequently be heat-treated, for example at a temperature of 1800‹ C., and/or graphitized, for example at a temperature of 2700‹ C. The graphitisable carbon may be calcined or uncalcined coke. The process may be modified by adding particles of a carbonaceous nuclear fuel material, for example particles of uranium dicarbide coated with pyrolytic carbon and/or silicon carbide, to a mixture of graphite powder and binder to produce a fuel for a nuclear reactor.

Abstract: 931,268. Electromechanical filters. TELEFUNKEN G.m.b.H. Aug. 20, 1959 [Aug. 23, 1958], No. 28499/59. Class 40 (8). [Also in Group XXIII] The core 4 of a magnetostrictive transducer, made e.g. of ferrite, is secured to the end surface of a mechanical resonating system 1, 2, 3, made e.g. of steel, by vitreous material 5, the surface of the resonator being provided with one or more projections 6 whereby a minimum thickness of the vitreous layer 5 is determined. The vitreous material is applied in fluid form at about 650‹ C. to the cylindrical parts 3, 4 and the parts pressed together to squeeze out excess material. The projection 6 prevents the formation of a vitreous layer which is too thin to withstand cooling stresses due to differences in thermal expansion coefficients. The construction shown is a filter comprising half-wavelength resonators 1 welded, screwed to, or integral with quarter-wavelength coupling members 2. The output transducer (not shown) is similar to the input transducer.

Title: o-hydroxy-dihydro-quinoline carboxylic acids
Filed: 1951-12-06
Abstract: The invention comprises compounds of the general formula <FORM:0700729/IV (b)/1> wherein R stands for an aliphatic saturated hydrocarbon radical. These compounds may be obtained by heating an alkali metal salt of p-(N-g -oxobutylamino)-salicylic acid or its homologues in an inert solvent and acidifying the reaction mixture. The p-(N-oxoalkylamino)-salicylic acid may be obtained by reacting an a .b -unsaturated ketone or a b -halogeno ketone to react on p-amino-salicylic acid or its salts.  p-(N - g  - oxobutyl - amino) - salicylic acid may be obtained by reaction between equimolecular amounts of p-amino-salicylic acid and vinylmethyl ketone or chloro- or bromo-ethylmethyl ketone.  Alternatively water may be added to the triple linkage in p-(N-3-butinylamino) salicylic acid or its salts under the influence of acid mercuric salts.  Treatment of p-amino-salicylic acid with vinyl acetylene in the presence of water, a water-miscible solvent and an acid mercuric salt, e.g. mercuric sulphate also yields p-(N-g -oxobutylamino) salicylic acid.  The reaction product without isolation may be used in the process of the invention.  In an example the sodium salt of p-amino-salicylic acid is reacted at 30 to 35 DEG  C. with vinylmethyl ketone in methanol and then stirred further up to 55 DEG  C. to yield on acidification dihydro - 4 - methyl - 7 - hydroxy - quinoline - 6 - carboxylic acid.

Title: Improvements in the manufacture of artificial filamentary material
Inventor: HILL FRANK BRENTNALL
IPC: D01D5/06
Filed: 1953-09-02
Abstract: <PICT:0787561/IV (a)/1> In wet-spinning wherein the filaments are drawn through and out of a narrow tube through which coagulating liquid flows, the filaments are drawn by a godet comprising a number of equally spaced parallel or nearly parallel thread-carrying bars. The bars are preferably cylindrical and are preferably supported at one end only, the other ends being left free or merely held by a spacing member.  As shown, filaments from the jet 5 are spun into coagulating liquid in extrusion chamber 4 and are drawn up the setting tube 10, also containing coagulating liquid, by godet 17 which comprises a number of cylindrical rods 20 carried at one end by a driven disc 18, which imparts stretch.  Excess coagulating liquid is removed from the filaments by a pigtail guide 16 and inverted funnel 15 as described in Specification 787,556.  The filaments then pass to washing device 21 comprising a pair of skew rollers 22 partly immersed in water, then over godet 26 to further washing baths or to a takeup device.  The further washing may be effected in an apparatus (Fig. 3, not shown), wherein the filaments are passed several times round a pair of rollers of which the lower roller is driven, cylindrical and is immersed in the washing liquid, and the upper is freely mounted and is either made up of a number of parallel bars or is a fluted roller, as described in Specification 787,558, or has any other shaped periphery which makes contact with the filaments at intervals along their length.  The invention is of particular value in the manufacture of cellulose acetate by extruding an acetone solution of cellulose acetate into an aqueous solution of diethylene glycol diacetate or of acetone, but it may be used in other wet-spinning processes, e.g. in the spinning of acetic acid solutions of cellulose acetate into aqueous acetic acid containing a high concentration of a salt such as an alkali metal acetate.
